Example 2:
. 45° Corner Installation. (Only available using Top Vent)
Attach a PEL-90 (90° elbow) directly onto the flue collar, and attach
it to the PEL-45 (45° elbow). Cut the PXT-18 to suit and insert it into
the PEL-45. Slide the fireplace into position, and then connect it to
the exterior termination.

45° or less Corner Installation. (Only available using Top Vent).
Use a PTO-3 termination and an PFL-1 or PFL-2 (12" or 24"
compressed length) and a frame, if appropriate. Flex may be turned to
obtain desired degree of angle required but must not exceed 45°.

Example 3:
Rigid sections and an elbow used in conjunction with 3 ft. flex section
(PFL-3) will, when extended in a five foot chase, allow for a maximum
horizontal run of twelve and one-half feet from the centre of the fireplace
to outside wall and a minimum of 7'6" when retracted in opposite direction
(see Figure 12 and 13).
"C" flex sections and "D" rigid sections may be used in conjunction with
one another to obtain different possible horizontal length installations.
NOTE: Flex section with no vertical rise must not exceed maximum
horizontal length of 3 feet (see Figure 14). Flex runs over 6' feet must
fall within the limits set by the venting graph, and must have a minimum
vertical rise of 3" per foot of flex.
